Thanks to a large number of locks ropes very flexible, at the
same time possess high strength characteristics and the reduced
friction between external provoloka in locks and a surface of
streams of blocks. And the different directions of a twist of
external and inside layers of locks are prevented by torsion of a
rope around an axis.

External locks of a rope after a twist pass through blooming
rollers thanks to what the lock is condensed - metal
cross-sectional area increases, the form of a lock becomes more
smooth, roundish, it gives the following advantages:

wear resistance a provolok to attrition increases, wear of
streams of blocks, high strength characteristics of a rope
decreases, resistance of a rope to cross crush is increased

These advantages allow to increase service life of a rope and to
considerably lower operational costs
